Dental abutment



FIG. 1 is a front view of a dental abutment showing our new design;

FIG. 2 is a top view thereof;

FIG. 3 is a bottom view thereof;

FIG. 4 is a right side view thereof;

FIG. 5 is a left side view thereof; and,

FIG. 6 is a cross-sectional view taken along the line A-A in FIG. 4.

The dash-dot dash broken lines immediately adjacent the claimed areas represent the bounds of the claimed design while all other broken lines represent environmental structure and are for illustrative purposes only; the broken lines form no part of the clamed design.

A rear view is omitted because it appears symmetrically to a front view. 

The ornamental design for a dental abutment, as shown and described.
